2016-07-22scripts: Fix size mismatch of kexec_purgatory_sizeTautschnig, Michael
bin2c is used to create a valid C file out of a binary file where two symbols will be globally defined: <name> and <name>_size. <name> is passed as the first parameter of the host binary. Building using goto-cc reported that the purgatory binary code (the only current user of this utility) declares kexec_purgatory_size as 'size_t' where bin2c generate <name>_size to be 'int' so in a 64-bit host where sizeof(size_t) > sizeof(int) this type mismatch will always yield the wrong value for big-endian architectures while for little-endian it will be wrong if the object laid in memory directly after kexec_purgatory_size contains non-zero value at the time of reading. This commit changes <name>_size to be size_t instead. Note: Another way to fix the problem is to change the type of kexec_purgatory_size to be 'int' as there's this check in code: (kexec_purgatory_size <= 0) Signed-off-by: Michael Tautschnig <tautschn@amazon.com> Cc: Vivek Goyal <vgoyal@redhat.com> Acked-by: Dave Young <dyoung@redhat.com> Signed-off-by: Michal Marek <mmarek@suse.com>
2016-07-22kbuild: make samples depend on headers_installArnd Bergmann
Olof's build test setup keeps failing to compile arm64 kernels because of a toolchain that uses outdated kernel headers: /work/build/batch/samples/seccomp/bpf-fancy.c:13:27: fatal error: linux/seccomp.h: No such file or directory This is of course something he could change, but it also indicates that others may run into the same problem. Running 'make headers_install' avoids the issue by ensuring that the kernel headers are put into the $(objdir)/usr/include path before we build the samples. The same problem happened for the Documentation build in the past and was fixed up with commit 8e2faea877eb ("Make Documenation depend on headers_install"). This adds an identical Makefile dependency for the samples/ subdirectory. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Marek <mmarek@suse.com>
2016-07-22PM / hibernate: Introduce test_resume mode for hibernationChen Yu
test_resume mode is to verify if the snapshot data written to swap device can be successfully restored to memory. It is useful to ease the debugging process on hibernation, since this mode can not only bypass the BIOSes/bootloader, but also the system re-initialization. To avoid the risk to break the filesystm on persistent storage, this patch resumes the image with tasks frozen.

2016-07-22coccicheck: add support for requring a coccinelle versionLuis R. Rodriguez
Enable Coccinelle SmPL patches to require a specific version of Coccinelle. In the event that the version does not match we just inform the user, if the user asked to go through all SmPL patches we just inform them of the need for a new version of coccinelle for the SmPL patch and continue on with the rest. This uses the simple kernel scripts/ld-version.sh to create a weight on the version provided by spatch. The -dirty attribute is ignored if supplied, the benefit of scripts/ld-version.sh is it has a long history and well tested. While at it, document the // Options stuff as well. v4: Document // Options and // Requires as well on Documentation/coccinelle.txt. Signed-off-by: Luis R.

2016-07-22scripts: add Linux .cocciconfig for coccinelleLuis R. Rodriguez
Coccinelle supports reading .cocciconfig, the order of precedence for variables for .cocciconfig is as follows: o Your current user's home directory is processed first o Your directory from which spatch is called is processed next o The directory provided with the --dir option is processed last, if used Since coccicheck runs through make, it naturally runs from the kernel proper dir, as such the second rule above would be implied for picking up a .cocciconfig when using 'make coccicheck'. 'make coccicheck' also supports using M= targets.If you do not supply any M= target, it is assumed you want to target the entire kernel. The kernel coccicheck script has: if [ "$KBUILD_EXTMOD" = "" ] ; then OPTIONS="--dir $srctree $COCCIINCLUDE" else OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE" fi KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases the spatch --dir argument is used, as such third rule applies when whether M= is used or not, and when M= is used the target directory can have its own .cocciconfig file. When M= is not passed as an argument to coccicheck the target directory is the same as the directory from where spatch was called. If not using the kernel's coccicheck target, keep the above precedence order logic of .cocciconfig reading. If using the kernel's coccicheck target, override any of the kernel's .coccicheck's settings using SPFLAGS. We help Coccinelle when used against Linux with a set of sensible defaults options for Linux with our own Linux .cocciconfig. This hints to coccinelle git can be used for 'git grep' queries over coccigrep. A timeout of 200 seconds should suffice for now. The options picked up by coccinelle when reading a .cocciconfig do not appear as arguments to spatch processes running on your system, to confirm what options will be used by Coccinelle run: spatch --print-options-only You can override with your own preferred index option by using SPFLAGS. Coccinelle supports both glimpse and idutils. Glimpse had historically provided the best performance, however recent benchmarks reveal idutils is performing just as well. Due to some recent fixes however you however will need at least coccinelle >= 1.0.6 if using idutils. Coccinelle carries a script scripts/idutils_index.sh which creates the idutils database with as follows: mkid -i C --output .id-utils.index If using just "--use-idutils" coccinelle expects your idutils database to be on the top level of the kernel as a file named ".id-utils.index". If you do not use this you can symlink your database file to it, or you can specify the database file following the "--use-idutils" argument. Examples: make SPFLAGS=--use-idutils coccicheck This assumes you have $srctree/.id-utils.index, where $srctree is the top level of the kernel. make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck Here you specify the full path of the idutils ID database. Using .cocciconfig is possible, however given the order of precedence followed by Coccinelle, and since the kernel now carries its own .cocciconfig, you will need to use SPFLAGS to use idutils if desired. v4: o Recommend upgrade for using idutils with coccinelle due to some recent fixes. o Refer to using --print-options-only for testing what options are picked up by .cocciconfig reading. o Expand commit log considerably explaining *why* .cocconfig from two precedence rules are used when using coccicheck, and how to properly override these if needed. o Expand Documentation/coccinelle.txt v3: Expand commit log a bit more Signed-off-by: Luis R.

2016-07-22coccicheck: replace --very-quiet with --quiet when debuggingLuis R. Rodriguez
When debugging (using --profile or --show-trying) you want to avoid supressing output, use --quiet instead. While at it, extend documentation for SPFLAGS use. For instance one can use: $ export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci $ make coccicheck DEBUG_FILE="poo.err" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c Expand Documentation/coccinelle.txt as well. v4: expand Documentation/coccinelle.txt v3: rebased, resolve conflicts, expand Documentation/coccinelle.txt v2: use egrep instead of the *"=--option"* check, this doesn't work for disjunctions.

2016-07-22coccicheck: enable parmap supportLuis R. Rodriguez
Coccinelle has had parmap support since 1.0.2, this means it supports --jobs, enabling built-in multithreaded functionality, instead of needing one to script it out. Just look for --jobs in the help output to determine if this is supported and use it only if your number of processors detected is > 1. If parmap is enabled also enable the load balancing to be dynamic, so that if a thread finishes early we keep feeding it. stderr is currently sent to /dev/null, addressing a way to capture that will be addressed next. If --jobs is not supported we fallback to the old mechanism. We expect to deprecate the old mechanism as soon as we can get confirmation all users are ready. While at it propagate back into the shell script any coccinelle error code. When used in serialized mode where all cocci files are run this also stops processing if an error has occured. This lets us handle some errors in coccinelle cocci files and if they bail out we should inspect the errors. This will be more useful later to help annotate coccinelle version dependency requirements. This will let you run only SmPL files that your system supports. Extend Documentation/coccinelle.txt as well. As a small example, prior to this change, on an 8-core system: Before: $ export COCCI=scripts/coccinelle/free/kfree.cocci $ time make coccicheck MODE=report ... real 29m14.912s user 103m1.796s sys 0m4.464s After: real 16m22.435s user 128m30.060s sys 0m2.712s v4: o expand Documentation/coccinelle.txt to reflect parmap support info o update commit log to reflect what we actually do now with stderr o split out DEBUG_FILE use into another patch o detect number of CPUs and if its 1 then skip parmap support, note that if you still support parmap, but have 1 CPU you will also go through the new branches, so the old complex multithreaded process is skipped as well. v3: o move USE_JOBS to avoid being overriden v2: o redirect coccinelle stderr to /dev/null by default and only if DEBUG_FILE is used do we pass it to a file o fix typo of paramap/parmap Signed-off-by: Luis R.

2016-07-22coccicheck: make SPFLAGS more usefulLuis R. Rodriguez
SPFLAGS is set early, it means that any heuristics done on coccicheck cannot be overridden currently. Move SPFLAGS after OPTIONS and set this at the end.

2016-07-22x86/boot: Simplify EBDA-vs-BIOS reservation logicAndy Lutomirski
Both the intent and the effect of reserve_bios_regions() is simple: reserve the range from the apparent BIOS start (suitably filtered) through 1MB and, if the EBDA start address is sensible, extend that reservation downward to cover the EBDA as well. The code is overcomplicated, though, and contains head-scratchers like: if (ebda_start < BIOS_START_MIN) ebda_start = BIOS_START_MAX; That snipped is trying to say "if ebda_start < BIOS_START_MIN, ignore it". Simplify it: reorder the code so that it makes sense. This should have no functional effect under any circumstances.

2016-07-22i40e: Move the mutex lock in i40e_client_unregisterCatherine Sullivan
We need to lock the client list around the i40e_client_release call to prevent the release from interrupting the client instances while they are being added.

2016-07-22i40e: refactor Rx filter handlingMitch Williams
Properly track filter adds and deletes so the driver doesn't lose filters during resets and up/down cycles. Add a tracking mechanism so that the driver knows when to enter and leave promiscuous mode. Implement a simple state machine so the driver can track the status of each filter throughout its lifecycle. Properly manage the overflow promiscuous state for the each VSI, and provide a way for the driver to detect when to exit overflow promiscuous mode. Remove all possible default MAC filters that the firmware may have set up so that the driver can manage these correctly, particularly when VLANs come into play. Remove the LAA flag for filters; instead just send whatever we get through set_mac to the firmware as the LAA for wakeup purposes. Finally, add the state of each filter to debugfs output so we can see what's going on inside the driver's pointy little head.
